Showers Possible By End Of Week



View looking toward Rincons/Redington Pass at 6:55 am MST this morning.

The GEFS plumes for rainfall amounts at airport (from 06 UTC runs - above) indicate showery periods into early next week. Note the wide range of values and timing, so things are a bit uncertain at this time. The plumes from same runs for winds (below) indicate the possibility of some gustiness and stronger speeds for tomorrow and Thursday.


The GFS 500 mb forecast (above from 06 UTC run shows a strong, closed low over Arizona and southern California at 12 UTC on the 15th (Friday).


The precipitation forecast from the 06 UTC WRF-GFS run (above) indicates light precipitation amounts for eastern Pima County through 11:00 pm on the 16th (Saturday). The morning NWS TUS forecast for the airport is shown below for Thursday through Saturday, with highest POPs on Friday. It should be an interesting end-of-week and weekend.
